Dropdowns

Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.

Examples

Wrap the dropdown’s toggle (your button or link) and the dropdown menu within
.dropdown, or another element that declares
position: relative;. Dropdowns can be triggered from
<a> or
<button> elements to better fit your potential needs.

Single button dropdowns

Any single
.btn can be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either
<button> elements:

Split button dropdowns

Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of
.dropdown-toggle-split for proper spacing around the dropdown caret.

We use this extra class to reduce the horizontal
padding on either side of the caret by 25% and remove the
margin-left that’s added for regular button dropdowns. Those extra changes keep the caret centered in the split button and provide a more appropriately sized hit area next to the main button.
